Approved August 17, effective March 15, 2027. Two sibling filings, one move: Liberty Mutual raises California commercial-package (liability) rates an average 25.8% across 21,628 policyholders and $68.8M in premium, and lifts a companion general-liability book 26.3% across another 8,519 policyholders and $14.6M — roughly $83.4M of California liability premium re-rated together. The package filing's own indication was 51.9%, so even a 25.8% average is barely half the stated need, and the increase concentrates sharply by geography: base rates spike about 60% in the Bay Area. Coverage tightens alongside the rate — new mandatory Endocrine Disruptors and Respirable Dust/Vapors exclusions and a revised Fungi/Bacteria exclusion apply to both books. Manufacturers, wholesalers, retailers, restaurants, real-estate and repair-shop accounts on Liberty paper in California should expect the rate, the geography and the narrower coverage all at once.
